We Investigate The Ground State Properties And The Nonequilibrium Dynamics Of A Lattice Trapped Bosonic Mixture Consisting Of An Impurity Species And A Finite-Sized Medium. For The Case Of One As Well As Two Impurities We Observe That, Depending On The Lattice Depth And The Interspecies Interaction Strength, A Transition From A Strongly Delocalized To A Localized Impurity Distribution Occurs. In The Latter Regime The Two Species Phase Separate, Thereby Forming A Particle-Hole Pair. For Two Impurities We Find That Below A Critical Lattice Depth They Are Delocalized Among Two Neighboring Outer Lattice Wells And Are Two-Body Correlated. This Transition …

We Unravel The Correlated Tunneling Dynamics Of An Impurity Trapped In A Double Well And Interacting Repulsively With A Majority Species Of Lattice Trapped Bosons. Upon Quenching The Tilt Of The Double Well It Is Found That The Quench-Induced Tunneling Dynamics Depends Crucially On The Interspecies Interaction Strength And The Presence Of Entanglement Inherent In The System. In Particular, For Weak Couplings The Impurity Performs A Rather Irregular Tunneling Process In The Double Well. Increasing The Interspecies Coupling It Is Possible To Control The Response Of The Impurity Which Undergoes A Delayed Tunneling While The Majority Species Effectively Acts As …
